This problem has been solved! The exception, of course, being the hydrogen's. From-http://en.wikipedia.org/wiki/Acetic_Acid -In the form of vinegar, acetic acid solutions (typically 4% to 18% acetic acid, with the percentage usually calculated by mass) are used directly as a condiment, and also in the pickling of vegetables and other foods. C:4×2=8 H:1×6=6 O:6. Correct Lewis structure for acetic acid is: Consider two hydrogen atoms A and B with electron e A and e B respectively. The amount of acetic acid used as vinegar on a worldwide scale is not large, but is by far the oldest and best-known application. In the full Lewis structure, each carbon atom satisfies the octet rule, and there are no unshared electron pairs in the molecule. About this Site | Report a Problem | Comments & Suggestions, Stoichiometry: Moles, Grams, and Chemical Reactions. So, there are 4 lone pairs in the Lewis structure.
